To all whom t may concern:

Be it known thatl, EDWARD R. ANDER- soN, a citizen of the United States, and resident of Blackstone,-in the county of Nettoway and State of Virginia, have invented certain new and useful Improvements in Gil-Burners, of which the following is a specification.

This invention relates to burners for developing heat from the consumption of lkerosene -or yother distillates of petroleum,

and particularly to that type of such burners which utilize a portion of thev heat to properly ycondition the yfuel for efficient burning.` 1

The invention has for its object to produce a device of simple and eiiicientconstruction and one in which carbonizin will be reduced to ra minimum, but w ich may be conveniently cleaned when carbonizing takes place; y

To these ends, the invention employs a fuel heater provided with a protracted chan Ywall of the primary chamber inwhich the oil is in a fluid state; the primary and secondary chambers being 'each provided with removable closures giving access to the chambers for cleaning them, and the passage between the chambers being so related to one of said closures as to'be accessible through said closure. In the preferred embodiment, the secondary chamber underlies the pr1- vmary chamber for a part only of the length of the latter, and to give protection to the primary chamber for the remainder of its length, the body of the heater is increased in thickness. This arrangement insures the advantages of having the fuel outlet at an intermediate position where it is more or less .ch-arge pi surrounded by the flame and, therefore, subl jected to heating action and at the same time admitting1 of a pair of burner tubes being supporte from a single connection with corresponding reduction in the number of connecting parts. A'In the preferred embodiment of the'invention, the metal is distrib- Patented J une 10, 1913.

uted so as to Yprovide a comparatively ythin wall above the primary chamber and relatively thicker walls between the chambers a d beneath the secondary chamber, so that th heatingei'ect is more evenly distributed and; the life of the device is greatly increased.

The .invention will be fully understood upon reference to the Vaccompanying drawmLin whichonthe line 2-2 of Fig. 1, and Fig. 3 is a Vsection on the line 3 3 of Fig. 1.

. 1v represents the body of the burner which 1s constructed preferably of an integral vcasting having a. primary heating chamber 2 with an oil inlet 3 at one end and with a secondary heating chamber 4 communicating with the chamber 2 through the port 5 at the other end. The chamber 4 underlies the chamber 5 and communicates at its end remote from the port4 5 with the fuel' disep 6 which carries the burner tubes 7. he chamber 4, particularly when it is desired Vto use a pair of burner tubes 7,

gure 1 is a vertical longitudinal section o f the improved burner; Fig. 2 is a section extends but apart of the length of the chamber 2 in-order that its outlettube 6 may occupy an intermediate position, and in such case, the body- 1 is provided with a thickened protecting portion 1* beneath that portion of the chamber 2 which is not protected by the chamber 4. The upper wall of the chamber 2 is relatively thin, so that the burning gases which more or less surround the entire burner when used in a stove, for instance, Will have` an eiicient heating effect upon the fuel of the primary chamber; but

the side walls 1" and the bottom wall 1 are relatively much thicker, so that the imping- `ing Hame from the burner tube 7 cannot de" velop excessive heat on any restricted area ofI the heating chambers .and cause undue carbonizing of the burner. Carbonizing is essentially a precipitation of mechanically v suspended particles' in the fuel and is aggratime for raising the temperature of the me-l VIl() vated by too sudden raising of the temperature, as for instance by the liquid striking chanically mixed solid matters, precipitation is greatly reduced and such matters escape through the burner tubes andare consumed.

' To facilitate cleaning the burner after long continued use, the chambers 2 and 4 are proded with end closures 8 and 9, preferably in the .form of plugs which give access in a straight line with the chambers. The port 5 is located adjacent to one or both of these plugs so as to be accessible through the opening provided by removal of a plug and 1s preferably inclined toward one of the plugs to. facilitate introducing a cleaning instrument. The outlet, tube 6 and the burner tub s 7 with caps 7 a on the latter are all assemb ed by threading,'so that the parts can bereadily separated for cleaningi If the chamber 4 extended the full len of the chamber 2, as for instance when the outlet tube 6 is at one end and a single burner tube 7 extends beneath the chamber 4:, the thickened portion 1il can be correl pondingly reduced in length or omitted altogether.

In use, the burner will preferably be introduced in proper position in a lire-place or stove as is common with burners of this general type.

The burner tubes 7 will be provided with any desired number of small openings 7b for escape of fuel suitably directed to develop -any desired spreadin of the flame.

The bottom of the cham r 2 is inclined from the intake 3 to the port 5, and the bottom of chamber 4 is inclined fromthe port 5 to the outlet (conveniently attained by inclining the .whole chamber), so that complete drainage results.
